benifits of super vs turbo

[mysweetvt]

I have been quoted $9500 for a complete turbo setup for my vt calais,which would be quite unique, but i know you can get superchargers for much cheaper than this, what are the benifits of each against eachother? im looking for power but most of all i want it to last a long time and not need checking up on all the time, and to handle some curry down the quater mile. My calais is a 3.8 v6. Thanks rohan

Basically the turbo will develop more power, the supercharger will develop it early. So the turbo should be faster in a straight line, however it you put that much cash into a supercharged v6 it would be pretty quick. I would like at a different model with a ls1 for that amount before pouring cash into a normal ecotec.

The normal ecotec is a l36 and the supercharged engine is a l67. There are a fair amount of different components in the two engines. Including fuel delivery etc. The l36 is meant to be able to handle a supercharged setup but once you increase boost the l36 is not your best option. One of the differences is the compression ratio, which apparently needs to be different for forced induction.

Have a read over the fit website as they have a heap of info on the whole deal.

In particular read this, Forced Induction Technologies - Australia's V6 Supercharged Specialists

question 22

super - no lag, but used engine power to drive it. cheeper

turbo - lag. no powerloss to run turbo. deerer.

insurance may also be a bit unhappy with having a turbo commodore.

if you do turbo it, PLEASE dont put a gay blowoff valve on it, nothing is funnier than a vl turbo phhhhhhhsssssssh tu tu tu

go the turbo mate nufin more exciting then seeing a v6 turbo commdoore go down the quarter , everyone has a cammed ls1 that runs 12 and everyone has l67's with high boost and and intercolled but how often do u see a turbo ecotec ? , i rkeon the 9500 is well worth it and makes your car alot more original

[Burnout_bro]

9500??? wow thats steep, do some research and turbo it yourself, well not yourself, get brackets and pipes made buy and intercooler and a decent turbo wastegate and manifold and you will be cruising in parts i reckon it would set you back 4k for a real decent setup. and about 800 for someone too put it on properly.

if u want ur car 2 last a long time dont get either stick 2 how it is

[Commotion]

you can have my setup for 5g, and includes everything cept sump and tune. including 3" exhaust, polished aluminium pipework, ceramic coated manifolds and turbo housing. polished comp cover. reversed plenum, 32lb injectors. i also have a larger comp cover and wheel just hasnt been fitted. with larger comp cover and larger injectors would easily see 220rwkw. boost pulls hard and full at 3000rpm running 8psi.

Wouldn't it be better if you just drop a V8 in there??
I mean if you are just looking for more power.

If you want your car to be quite unique, then turbo is good but you need to strengthen your engine's internals before you chuck the turbo on.

[holden007]

Turbo will cause you trouble in the long run, thats why the engine should be rebuilt (strengthened).

You want something in the long run with power, go V8 (LS1+) as AttaBoy as mentioned.

Has power on the spot, has standard components so it doesnt cost an arm and leg to service (cost wise) and you'll have that nice crisp V8 sound (i.e with exhaust).

i dunno where you people are getting the idea of lag, in most cases the v6's are using a T3/T4 which is very daily driveable and come to the line to race, bring the revs up to 2500rpm and bang your gone and even on the highway overtaking there is no lag, with my 5 speed i knock it back to 4th before i overtake and just before i step out its back to 3rd and i'm around the car quicker then you know it.

so with a 2500rpm stally for a auto there would be pretty well no lag off the line. and you can run usually up to 7-9psi before you will look at doing the internals

[Commotion]

lag is only something that occurs when a motor is built to make big power. being low compression and the types of cams etc causes horrid power down low until boost which then increases the mean affective pressure making all the power up high. you stick a turbo on a standard motor there is no lag its just the same power that it had prior to turbo up untill 2500-3000. my car has the intake pressure just passing the 0 mark at 2500 and is at 8psi by 2900-3200 depending. you want lag you get a centrifical blower. you have to wait till redline before you get your max boost and at 3g where mine is making max boost a centrifical blower would only be making a pound or two. plus when at the drags that bit of dosile power low in the revs can give the car time to get some momentum before all the power comes on. i hate it when people use the term lag to bag out turbos as the obviouldy have no idea about what they are talking about.

I've been enjoying the SC concept for some years now, perfectly suited to the stock engines and there is no sudden rush or rise, just controllable torque with more than enough stick to knock a couple of seconds of the stock times.

And the ease, a few hours and the enjoyment comes right away .........

You would probably expect I would say the above ........ however thats just how it is. And its way easy on the car too.

Price: $4995 all the time including a tune and if you DIY you are on the road to glory right away with no more to pay, 10psi boost.

Insurance on cars with Raptor seem to be getting quite reasonable rates through shannons Insurance too.

I've owned both turbo cars and s/c cars. The S/c car was so much more of a pleasure to drive, can town drive with no issue but have every bit of hp available when you touch the fun button. With my Turbo setups, they were too nothing then bam. It doesn't give the same effect of power as a s/c.

Besides, nothing beats the sound of a nice whine.
